A Uniform Analysis of Debris Disks with the Gemini Planet Imager I: An Empirical Search for Perturbations from Planetary Companions in Polarized Light Images

Kavli Affiliate: Bruce Macintosh | First 5 Authors: Katie A. Crotts, Brenda C. Matthews, Gaspard Duchêne, Thomas M. Esposito, Ruobing Dong | Summary: The Gemini Planet Imager (GPI) has excelled in imaging debris disks in the near-infrared. The GPI Exoplanet Survey (GPIES) imaged twenty-four debris disks in polarized $H$-band light, while other programs observed half […]

FlexKnot as a Generalised Model of the Sky-averaged 21-cm Signal at z ~ 6-30 in the Presence of Systematics

Kavli Affiliate: George Efstathiou | First 5 Authors: Emma Shen, Dominic Anstey, Eloy de Lera Acedo, Anastasia Fialkov, | Summary: Global 21-cm experiments are built to study the evolution of the Universe between the cosmic dawn and the epoch of reionisation. FlexKnot is a function parameterised by freely moving knots stringed together by splines. Adopting […]

Fate of supernova progenitors in massive binary systems

Kavli Affiliate: Shunsaku Horiuchi | First 5 Authors: Tomoya Kinugawa, Shunsaku Horiuchi, Tomoya Takiwaki, Kei Kotake, | Summary: How massive stars end their lives depends on the core mass, core angular momentum, and hydrogen envelopes at death. However, these key physical facets of stellar evolution can be severely affected by binary interactions. In turn, the […]

Language-guided Few-shot Semantic Segmentation

Kavli Affiliate: Jing Wang | First 5 Authors: Jing Wang, Yuang Liu, Qiang Zhou, Fan Wang, | Summary: Few-shot learning is a promising way for reducing the label cost in new categories adaptation with the guidance of a small, well labeled support set. But for few-shot semantic segmentation, the pixel-level annotations of support images are […]

GBT/Argus Observations of Molecular Gas in the Inner Regions of IC 342

Kavli Affiliate: Sarah Church | First 5 Authors: Jialu Li, Andrew I Harris, Erik Rosolowsky, Amanda Kepley, David Frayer | Summary: We report observations of the ground state transitions of $^{12}$CO, $^{13}$CO C$^{18}$O, HCN, and HCO$^+$ at 88-115 GHz in the inner region of the nearby galaxy IC 342. These data were obtained with the […]

Effect of Noise Estimation in Time-Domain Ringdown Analysis: A Case Study with GW150914

Kavli Affiliate: Lijing Shao | First 5 Authors: Hai-Tian Wang, Lijing Shao, , , | Summary: Accurate noise estimation from gravitational wave (GW) data is critical for Bayesian inference. However, recent studies on ringdown signal, such as those by Isi et al. [1], Cotesta et al. [2], and Isi and Farr [3], have encountered disagreement […]

Forecast of joint analysis of cosmic shear and supernovae magnification from CSST and LSST

Kavli Affiliate: Hu Zhan | First 5 Authors: Ye Cao, Bin Hu, Ji Yao, Hu Zhan, | Summary: Cosmic shear and cosmic magnification reflect the same gravitational lensing field. Each of these two probes are affected by different systematics. We study the auto- and cross-correlations of the cosmic shear from the China Space Survey Telescope […]

Narrow spectrum in repeating fast radio burst

Kavli Affiliate: Renxin Xu | First 5 Authors: Wei-Yang Wang, Yuan-Pei Yang, Hong-Bo Li, Jifeng Liu, Renxin Xu | Summary: Fast radio bursts (FRBs) can present narrow-band spectra with a variety of polarization properties. We study spectral properties from perspectives of intrinsic radiation mechanisms by invoking bunching mechanism and perturbations on charged bunches moving at […]
